A shaft (5) drives a rotary body (6), slider (7), guiders (8)(9) by means of device (A-1). A Plunger pumps (11)(11') are severably connected to the rotaty body (6) of cylinder type, the pamps are resp. supported at the rotaty plate (10) by the slider or the guider. The inclination of a fixed in plate (12) is controlled with levrs (14)(15) actuated by a diln. ratio controlling dial (13) and is assocd. with reciprocation strokes. The stroke vol. is controlled by the diln. ratio controlling dial. An amt. of pumping for one plunger pump follows a sine curve with the fine variation.
